Catalog views return information that is used by the SQL Server Database Engine. Catalog Views are the most general interface to the catalog metadata and provide the most efficient way to obtain, transform, and present customized forms of this information. All user- available catalog metadata is exposed through catalog views.

Cloud data center doesn’t require experts to operate it, but it requires skilled people to see the maintenance, maintain the workloads and to keep the track of the traffic. The labor cost is 6% of the total cost to operate the cloud data center. Power distribution and cooling of the datacenter cost 20% of the total cost. Computing cost is at the end and is the highest as it is where lots of resources and installation has to be done. It costs the maximum left percentage.

There are many algorithms that can be used to analyze the database to check the maintenance of all the data sets that are already present. The different types of cluster models include as follows:

- Connectivity models: these are the models that connect one cluster to another cluster. This includes the example of hierarchical clustering that is based on the distance connectivity of one model to another model. 

- Centroid models: these are the models that are used to find the clusters using the single mean vector. It includes the example of k-means algorithm.

- Distribution models: it includes the specification of the models that are statistically distributed for example multivariate normal distribution model.

- Density models: deals with the clusters that are densely connected with one another in the regions having the data space. 

- Group models: specifies the model that doesn’t provide the refined model for the output and just gives the grouping information

No problem. We can use network marketing as an alternative. The company already has its strong network of customers who can spread the word about its products. They can encourage referral rewards for say every three customers who will buy our product or avail our service.

We can also announce a contest for the customers to buy the product and win a chance to get himself broadcasted for the product advertisement. We can ask them to send in their photo along with the contest application form which they get alongwith the product they buy. So we don’t have to pay them as we would otherwise have to pay to a celebrity.

There are 2 documents: 

FRD (functional requirement document) 

SDD (system design document) which can also be called TRS (Technical requirements specifications) 

Profitability control is a mechanism of monitoring the sales made, profits earned and expenditure incurred by a company. The relative profit earning capacity of a firm’s products and consumer groups can be determined via profitability control. Sometimes surpisingly, it may be found out by companies how a small proportion of their products and even customers actually account for a significant percentage of the company’s profits. This can be achieved through profitability control. At times when the companies earn surplus profits, then such profits may even be ploughed back or reinvested. This also forms part of profitability control.
